Section III - Battery Operation
The Kendall SCD™ 700 series compression system is designed to operate normally on AC line power or DC battery
power without interruption. There are three Battery Status Indicator LED's used to represent the charge level of the
battery. Once the controller is powered on, it may take the system a few seconds to establish communication with the
battery and display the charge level. The battery Indicator shown below is located in the upper right hand corner of
the user interface. See FIGURE 10.
Warning: If the ground integrity of the mains power cable is in question, the device should be operated
on battery power until the ground integrity can be insured.
